Product Details

The Gibson Performance Exhaust 5657 Dual Split Cat-Back Exhaust System delivers an aggressive, throaty exhaust note combined with meaningful performance gains for truck enthusiasts seeking both sound and power. This complete cat-back system is engineered to reduce exhaust backpressure, resulting in typical horsepower gains averaging 18-20 HP along with increased torque throughout the powerband.

Key Features:

  • Dual split rear exit design with polished stainless steel tips for an aggressive appearance
  • Cat-back design replaces restrictive factory exhaust from the catalytic converter back
  • Bolt-on installation with no welding required for hassle-free installation
  • Compatible with most aftermarket bumpers, roll pans, and trailer hitches
  • Deeper, more aggressive exhaust tone that intensifies under load and towing conditions
  • Durable stainless steel tip construction resists corrosion and maintains appearance

This system provides the perfect balance of performance and sound for drivers who want their vehicle to stand out. The straight-through rear exit design with dual tips creates a bold look while the optimized exhaust flow enhances throttle response and overall engine performance. Note that exhaust volume increases noticeably during acceleration and under towing loads.
